A method of cleaning and sanitizing surgical tools or surgical instruments and accessories in general, and a device configured to implement the method. The method includes the use of a an abrasive cleaning material, which is emitted under pressure and at high speed to abrade and remove substances that adhere to the surfaces of the instruments and accessories, and the pressure of which can be regulated according to the type of surface to be cleaned.

Reduced noise abrasive blasting assemblies and systems are described. The new assemblies and systems are comprised of standard blast hose, accelerator hose, couplings and nozzle. The improved abrasive blasting system maintains abrasive particle velocity while decreasing the exit gas velocity and consequently decreasing sound production. This is accomplished through an acceleration section with reduced inner diameter and sufficient length to provide the necessary abrasive particle velocity. The new system maintains the productivity and efficiency of conventional abrasive blasting systems but with greatly reduced acoustic noise production and reduces operator fatigue due to the lower weight of the carried portion of the system.

According to one implementation, a blast treatment device includes at least one nozzle that injects media toward a workpiece, a first tank that supplies the media to the at least one nozzle, a movement structure that moves the at least one nozzle and the first tank, and a second tank that supplies the media to the first tank. The second tank is not moved by the movement structure.

An apparatus for treating an interior surface of a workpiece comprising at least three nozzles ejecting treating material, with a first one and a second one ejecting the treating material substantially along first and second collinear lines. A third one of the nozzles ejects the treating material substantially along a third line substantially perpendicular to the first and second lines. The treating material ejected from the first one intersects with the treating material ejected from the second one at a first intersection area to radially deflect to form a first radial spray. The treating material ejected from the third one intersects with the first radial spray at a second intersection area to form a second radial spray of treating material. The interior surface of the workpiece adjacent the second intersection area is treated with the treating material of the second radial spray.

An enclosed booth is provided with a low pressure, high volume air pump that outputs a stream of air for sandblast cleaning. A venturi nozzle having a venturi restriction at the end is positioned at the distal end of a first flexible tube. A second flexible tube has an outlet positioned adjacent to the venturi restriction which therefore creates a vacuum to pull sand media from the reservoir into the airflow and eject it out of the outlet nozzle of the first hose. This provides a low pressure stream of sandblast media for cleaning various parts. A reservoir is positioned at the bottom of the booth which is filled with the sandblast media. After the sandblasting media is output from the outlet nozzle, it falls through a substrate having apertures therein and enters the reservoir again.
